Rich people delegate me.
Poor people use me to pay the bills.
Most things like me wet.
Expensive things like me dry.
Bodies want me at least once a day.
Children need me all the time.
I’d be out of business if no-one had a nose.
Every bloody thing in the house that walks, talks, breathes or sits inanimately in the wretched sink needs me again and again without end for no discernable reason whatsoever apart from to swallow mindless swathes of time and allow people at Proctor and Gamble to pay their bills so they can employ poor people to spend mindless swathes of time paying theirs.
What am I?
